M = (1,4)
N = (5,2)
For M, you simply move to 1 on the x axis abs for 4 you move on the y axis. Same does for N, for 5 you move on the x axis and for 2 you move on the y axis.
4 times 7 gets 28 and 7-4 gets you 3
All this means is (f(x)) + (g(x))
2x-1+ x^2-3x-2=
=== x^2 - x -3
From the statements given in the problem, we can say
that:
Final Score = (total of the remaining scores) * degree of
difficulty * 0.6
Therefore:
97.2 = (total of the remaining scores) * 4.0 * 0.6
total of the remaining scores = 40.5
Therefore the judges could have scored which has a total
of 40.5
